How to install eSIM on your iPhone or iPad

Open your aloSIM app and select “My eSIMs,” then choose the eSIM you wish to install.

Log into aloSIM > My eSIMs > Select your eSIM

As an iPhone user, you will see three eSIM installation methods: Automatic, QR code, and Manual. We recommend selecting “Automatic” since it’s the fastest and easiest method.

Begin Automatic eSIM installation (or view these instructions for QR code installation or manual installation)

Our in-app instructions will show a preview of how the process will look, and then you can begin the automatic eSIM installation.

Tap “Continue” to approve the eSIM installation

OPTIONAL: Label your travel eSIM so you can easily identify it later.

Example: USA trip, Europe (aloSIM), South Africa (Mom’s iPhone)

Asked to choose a default line for Cellular Data?

Still at home? Keep using your primary SIM for data
Traveling now? Switch to your travel eSIM for data

If you’re using iOS 26, you may be asked different questions.

Home or Abroad? Select ‘Abroad’ as this is a travel eSIM.
Type of plan? Select ‘Data Only‘ as this is a data-only eSIM.

Your eSIM is now officially part of your iPhone, just like a physical SIM card. (Except this one can’t be lost or damaged, and you can keep it in there forever eSIMs never expire.)

• Go to ‘Settings’ on your iPhone or iPad
• Select your eSIM and toggle it on
• Toggle on ‘Data Roaming’ for your eSIM
• Make your eSIM your cellular data source

Already on vacation? Your eSIM should connect now.
Leaving now? You’ll connect as soon as you arrive.

Your regular phone carrier may attempt to charge for data, calls, and texts while you’re on vacation, so please check your iPhone or iPad settings.

OPTION 1: Toggle off ‘Data Roaming’ for your primary SIM 
It won’t provide data, but calls and texts will still work. See details.

OPTION 2: Fully toggle off your primary SIM
It won’t provide data, calls, or texts. See details.

Inside your aloSIM app, select “My eSIMs,” then tap on the eSIM you want to install.

Log into aloSIM > My eSIMs > Select your eSIM

iPhone or iPad users can choose from Automatic, QR code, or Manual eSIM installation. While Automatic is the fastest method, you can also use this QR code installation method.

aloSIM app > My eSIMs > Select your eSIM > Installation > QR code

Scan the QR code to begin your eSIM installation.

If you need to scan the code off a different screen, select ‘Share code’ to send it to another device and scan it off that screen.

Our in-app instructions will show a preview of how the process will look, and then you can begin the automatic eSIM installation.

Tap “Continue” to approve the eSIM installation

OPTIONAL: Label your travel eSIM so you can easily identify it later.

On your iPhone or iPad, start by navigating to ‘Settings’ and then selecting ‘Cellular’ (sometimes called ‘Mobile’ or ‘Mobile Data’). In this section, you’ll scroll down below all available SIMs and select ‘Add eSIM.’

Settings > Cellular > Scroll down and select ‘Add eSIM’

The next step is choosing ‘Use QR Code,’ even though you’re not actually going to scan anything.

Settings > Cellular > Add eSIM > Use QR Code

Instead of scanning a QR code, you’re going to look at the very bottom of the screen and select ‘Enter Details Manually.’

Settings > Cellular > Add eSIM > Use QR Code > Enter Details Manually

Inside your aloSIM app, select “My eSIMs,” then tap on the eSIM you’re about to install. Then open your eSIM installation options.

aloSIM > My eSIMs > Select your eSIM > Installation

Under the ‘Manual’ installation tab, you’ll see two codes. Start by copying the first one — you can tap the little ‘toast’ icon (two overlapped squares) to copy it easily.

Copy the first code (SM-DP+ Address)

Go back to your installation screen. In the first field, paste the SM-DP+ Address you just copied.

Return to your aloSIM account and repeat the process to copy the second code (Activation Code) from your aloSIM account and paste the second code (Activation Code) on the installation screen.

There is no Confirmation Code, so you can leave that blank.

Our in-app instructions will show a preview of how the process will look, and then you can begin the automatic eSIM installation.
